PDM35

I found this tonight while searching for something else. It is a Sinclair PDM35 Digital Multimeter.

I see from a web search that it was released in 1977. I remember that I got it when I was still a teenager and that it was quite expensive but in those days cheap and small for what it did. Today you could buy something better for about £3.00.

I am a little surprised that it still works and has survived me and all those years.
